I've not found this to be a good flavor at any percentage. I did use it at 1 drop/30ml in one of my recipes, and it wasn't awful after a month. Still not "good" and honestly, I don't see ever using this again. Weird that their most expensive flavor is just so, ahem, well, not fantastic.
You can spare yourself the expense if you have some old Avon or maybe some Aqua Velva lying around
